Reusing solutions

I was reading where people were re using their acid pickle bath solutions as long PH and salinity were maintained and was wondering if the same could be done with lutan f solutions? Is it a good practice for either? It would be conservative with my chemicals. What about super safety solvent degreaser (Rittels)? Can it be re used as well?

All of the above!

It's not good to reuse your tanning solution. I dont recommend it. First of all - the tan should have been depleted and you have only a very small Salt content left. It's difficult to measure the Salt accurately and re-strengthen it. And you would have to totally replenish the tanning agent. If you use too much Salt then your finished skins may "weep" with moisture on damp humid days.
